Abstract

An electronics ordnance delivery system that has an electronics component encased within a potting material, which itself is within a housing exoskeleton. A deceleration sleeve receives the exoskeleton, and is designed to shear away during a bullet's entry into a target body such that the electronics component is successfully deployed and remains in the target even if a part of the bullet exits the target. The system also includes an outer jacket that is also designed to shear away. The system can include a core that assists in the deployment of the electronics ordnance within the target.

Description

This application claims priority to U.S. provisional application 62/860,639, filed Jun. 12, 2019. U.S. provisional application 62/860,639 and all other extrinsic references contained herein are incorporated by reference in their entirety.

FIELD OF THE INVENTION

The field of the invention is ordnance deployment systems.

BACKGROUND

The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Until now, attempts have been made to incorporate sensors and other types of electronics packages into bullets, especially for small arms. However, up until now, those efforts were unsuccessful due to the high g-loads and harsh impacts of the environments. Firing a bullet exerts tremendous amounts of forces, heat, and other environmental factors on the bullet and the contents of the bullet therein. Upon impact, the effect can be even worse, depending on the density of the target. For delicate electronics components such as sensors, transmitters, processors and circuit boards, these forces can be destructive and often result in rendering the electronics components inoperable.
Moreover, an additional challenge in deploying electronics packages within bullets has been successfully retaining the electronics components embedded within the target, even in situations where part of the cartridge exists the target.
Thus, there is still a need for a solution that successfully deploys and maintains electronics components in ballistics and ordnance within a target while protecting the sensitive electronics package contained therein.

SUMMARY OF THE INVENTION

The inventive subject matter provides apparatus, systems and methods in which an electronic ordnance delivery system includes an electronics component encased within a potting material. A housing exoskeleton is dimensioned to receive the electronics component within the potting material, and a deceleration sleeve receives the housing exoskeleton.
The deceleration sleeve has several grooves along the sides that extend rearwardly that, upon entry into a target, are caused to shear away to deploy the electronics component within a target.
The electronics ordnance delivery system can also include an outer jacket that receives the deceleration sleeve. The outer jacket has serrated sides that also shear away upon entry into a target body.
In embodiments, the ordnance delivery system also includes a core at the front end of the deceleration sleeve. The core can be a lead core, and can have a rounded tip shape, a hollow-point tip shape, a flat-tip shape, or other shape.
Various objects, features, aspects and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawing figures in which like numerals represent like components.

The following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.
FIG. 1 shows the components of bullet 100 in an exploded and assembled view, according to an embodiment of the inventive subject matter.
Bullet 100 includes an electronics component 110 which is enclosed within the housing exoskeleton 120 when the bullet is assembled. In the embodiment shown in FIG. 1, the electronics component 110 includes a transmitter and as such, is coupled to antenna 140 for signal transmission. As assembled, a core 160 is inserted into a first end of the deceleration sleeve 130. The core 160 is made of a material that deforms upon impact and entry into a target body. For example, core 160 can be a lead core or made from another suitable material (e.g., polymer, composite, copper, steel or other hard or soft metals).
The deceleration sleeve 130 encases the housing exoskeleton 120 which contains the electronics component 110, all of which are encased within the outer jacket 150. The outer jacket 150 is then incorporated to finish the assembly of bullet 100. However, it should be noted that in the assembled bullet the tip of core 160 is exposed and not completely enveloped by the outer jacket 150. This is visible from in FIG. 1.
As seen in FIG. 1, bullet 100, powder charge 200 and case and primer 300 are then assembled into the finished cartridge 400.
The electronics component 110 can be a tracking device designed to track the location of the device when active (e.g., GPS device or other location determination system). It typically includes a transmitter that can transmit data to a remote computer, such as to communicate the location data and other types of data. The electronics component 110 can also include components such as biomonitors (that can monitor biometric aspects of a target such as heartbeat, temperature, the type of target hit, etc.), microphones, etc. Typically, in addition to having hardware for the specific purpose(s) of the bullet 100 (e.g., sensors, transmitters, etc.) the electronics component 110 will include a processor and physical memory (e.g., RAM, ROM, flash memory, solid-state memory, etc.) that store the programming for the electronics component 110 to execute its functions. The electronics component 110 also includes a battery or other type of portable power supply to power the various parts of the electronics component 110.
The electronics component 110 shown in FIG. 1 is encased in a potting material that is shaped to fit within the housing exoskeleton 120. To encase the electronics component 110, the electronics component 110 is placed within a mold and the potting material then poured into the mold, enveloping the electronics component 110. The potting material then hardens around the electronics component 110 leaving the assembled electronics component 110 with the potting material in the proper shape to fit within the housing exoskeleton 120. Alternatively, the electronics component 110 can be placed within the housing exoskeleton 120 and the potting material poured into the exoskeleton 120 directly such that the potting material encases the electronics component and hardens in the shape of the inside of the exoskeleton 120.
The potting material can be a polymer or other material that can be shaped in this way. The electronics component 110 is seen in FIG. 1 inside the potting material for illustrative purposes. The potting material may be transparent or translucent, such that the electronics component 110 is visible, or it may be opaque such that the electronics component 110 inside is not visible.
The embodiment in FIG. 1 shows an antenna 140 that is external to the electronics component 110. The antenna 140 enables wireless communication to/from the electronics component 110 across various wireless communications technologies (e.g., WiFi, cellular communication along various spectrums (e.g., 4G, 5G, etc.), RF, Bluetooth, NFC, etc.).
It is contemplated that the electronics component 110 could have an internal antenna in addition to/instead of the external antenna 140. Having an internal antenna in addition to the external antenna 140 can provide the electronics component 110 with additional wireless communication modalities, and can allow for simultaneous data transmission among these modalities. For example, the external antenna 140 can be a long range RF antenna while the internal antenna could be a short-range antenna such as a Bluetooth or NFC antenna. Another benefit of having both an internal and external antenna is that, during deployment, the external antenna may become damaged. If this occurs, the internal antenna (which could be of the same or a different wireless technology) serves to provide a backup way for the electronics component 110 to transmit/receive data.
It is contemplated that the electronics component 110 can communicate with cellular towers, satellites, repeaters, networking devices, mobile devices, and other computer devices. Thus, the electronics component 110 can communicate directly with a controller's computing device or relay the signal indirectly via various types of communication technologies.
In embodiments, the electronics component 110 can communicate with other electronics components 110 of other bullets 100, forming an ad-hoc mesh wireless network. This can be used to relay a more complete representation of a situation to the controller's computing device.
This can also be used to relay the signal from one or more bullets 100 back to the controller's computing device. For example, a series of bullets 100 can be fired at various locations near the intended target at distances such that each bullet 100 is within communication range of two other bullets in a chain, such that the series of bullets 100 forms a communication chain that leads from the intended target back within communication range of the operator. In this way, the operator (which could also be the shooter) could track the location of the target with a cellphone or other small portable device that might only have short-range wireless communications capabilities.
FIG. 2 shows a close-up view of the housing exoskeleton 120. As seen in FIG. 2, the housing exoskeleton 120 has an open end 121 at the rear end dimensioned to fit the electronics component 110. On this same end 121, the housing exoskeleton 120 has a collar 122 extending outwardly from the body of the exoskeleton. The collar 122 is dimensioned such that the rear end of the deceleration sleeve contacts the collar 122, preventing the deceleration sleeve 130 from sliding rearward during the acceleration of the bullet when fired. The front end 123 of the housing exoskeleton is closed and solid, thus helping to protect the electronics component 110.
In embodiments where a deceleration sleeve 130 is not used, the housing exoskeleton 120 does not have the collar 122.
The housing exoskeleton 120 is made from a material that can resist the forces encountered by the bullet 100 during firing and impact to protect the enclosed electronics component 110. Suitable materials include aluminum, stainless steel, and other hard metals or materials. It is also contemplated that polymers can be used for the housing exoskeleton 120.
The thickness and/or the material of the housing exoskeleton 120 can vary depending on factors such as the intended target, the caliber of the ordnance, the weapon deploying the ordnance, and whether a deceleration sleeve 130 is used in the bullet 100. For situations where the impact forces are expected to be greater, the housing exoskeleton 120 has a greater thickness and/or is made from a harder material to offer greater protection to the electronic components 110.
FIG. 3 is a close-up view of the deceleration sleeve 130 of FIG. 1. The deceleration sleeve 130 is dimensioned to fit the lead core 160 at a front end 131, and have the housing exoskeleton 120 introduced at a rear end 132 such that the housing exoskeleton 120 is within the deceleration sleeve 130. As noted above, when the bullet is fully assembled, the rear end 132 of the deceleration sleeve 130 abuts the collar 122 of the housing exoskeleton 120, thus preventing the deceleration sleeve 130 from further rearward movement relative to the housing exoskeleton 120 during firing and flight. As seen in FIG. 3, the deceleration sleeve 130 includes a plurality of grooves or perforations 133 extending rearwardly from the front end 131 of the sleeve. Between the grooves 133, the side surface 134 is divided up into deceleration segments 135. In the embodiments shown here, the grooves 133 extend entirely through the side surface 134 of the deceleration sleeve 130. Suitable materials for the deceleration sleeve 130 include aluminum, copper, or other metals with suitable properties. The material should not be too hard or rigid such that the deceleration sleeve 130 is prevented from shearing.
In the embodiments shown here, the grooves 133 extend entirely through the outer side surface 134 of the deceleration sleeve 130. In other embodiments, the grooves 133 may not extend entirely through the outer surface 134 of the sleeve 130 all the way to the inside, but instead be sections of material of a smaller thickness than the regular thickness of the sleeve 130.
FIG. 4 provides a close-up view of the outer jacket 150. Outer jacket 150 has an opening at a front end 151 and is closed at a rear end 152. Along the length of the side surface, outer jacket 150 has a plurality of serrated lines 153 extending rearwardly from the front end 151. These serrated lines 153 are weaker sections of the outer surface of the jacket 150 that are sufficiently strong to hold the bullet closed during flight, but that fail and cause the jacket 150 to shear away during the impact/deployment procedures as discussed in greater detail below. In the embodiment shown in FIG. 4, the serrated lines 153 extend along the entire length of the side of outer jacket 150. However, in other embodiments, the serrated lines 153 extend rearwardly along the side of outer jacket 150 for a portion of the length.
In embodiments, the serrated lines 153 are disposed on the outer jacket 150 to align with the grooves 133 of the deceleration sleeve 130 when the bullet 100 is assembled. In other embodiments, the serrated lines 153 are not required to be aligned with the grooves 133.
The outer jacket 150 can be made from aluminum, copper or other suitable materials. The material should not be too hard or rigid such that the outer jacket 150 is prevented from shearing.
In embodiments where a deceleration sleeve 130 is not used, the outer jacket 150 is dimensioned to also receive core 160.
FIG. 5 illustrates the process in which the deceleration sleeve 130 and outer jacket 150 are activated such that the electronics component 110 is delivered within the target.
At step 1 of FIG. 4, the bullet 100 has been fired and is in flight.
At step 2, upon impact, the core 160 (e.g., a lead core) expands laterally as it is compressed by the force of the impact. The expanding core 160 causes the segments 135 of deceleration sleeve 130 to begin shearing outward. This also causes the outer jacket 150 to split and fan out along its perforations, which fail due to the forces exerted by the expanding lead core 160. Because the core 160 is not fully encased by either the deceleration sleeve 130 or the outer jacket 150 in the assembly of the bullet 100, it can push both components outward as it flattens causing this fanning effect.
The friction caused by the contact of the fanned-out sections of the deceleration sleeve 130 and outer jacket 150 with the target result in the slowing down of the electronics component 110 within the housing exoskeleton 120. As the deceleration sleeve 130 peels away from the housing exoskeleton 120, the housing exoskeleton 120 with the electronics component 110 is left deployed within the target as shown in step 3.
During the deceleration of step 2, the slowdown caused by the fanning out of the outer jacket 150 causes the jacket 150 to become separated from the housing exoskeleton 120. This causes the antenna 140 to become deployed and begin transmission. In embodiments such as the one discussed in greater detail below, a magnet is used to initiate transmission wherein the separation of the magnet from the proximity of the electronics component 110 causes the initiation of transmission.
The expanding core 160 is illustrated herein as having a conical shape. However, other shapes are contemplated such as hollow points, rounded tip, flat tip, etc.
In embodiments such as the one illustrated in FIG. 6 (which is a cross-section/cutaway view), a forward magnet 170 is incorporated into the bullet between the core 160 and the housing exoskeleton 120. The forward magnet 170 is used to hold a switch in electronics component 110 open until deployment within a target such that the electronics component 110 is only powered (and thus activated) when the bullet impacts with a target. Upon impact, the magnet 170 is separated from the housing exoskeleton 120. When the force exerted by the magnet is no longer present due to the separation, the switch within electronics component 110 is closed and the power from a power source (a battery) is provided to the electronics component 110 for function.
In other embodiments, a switch can be used instead of the magnet 170. In these embodiments, the switch is kept open with a mechanism that is separated from the switch upon the separation, similar to the switch. The switch is biased to closed such that when the mechanism is separated from the switch, the switch closes thus completing the circuit and providing power from the power source to the electronics component 110.
It should be noted that the illustration of FIG. 6 is prior to the sealing of the outer jacket 150. To finish the manufacture of the bullet 100, the outer jacket 150 is shaped to follow the front shape of the core 160 and sealed. In the embodiment shown in FIG. 6, the assembly also includes a gas check 180 rearward of the outer jacket 150.
In alternative embodiments of the inventive subject matter, the bullet 100 can be assembled without a deceleration sleeve 130. In these embodiments, the thickness of the housing exoskeleton 120 is increased to provide adequate protection to the electronics component 110. In these embodiments, the front of the bullet can also be modified to assist in slowing the bullet after impact with the target. For example, a hollow-point core 160 (such as a hollow-point lead core) can be used to assist in slowing the bullet after it enters the target.
It is contemplated that the inventive subject matter can be used with bullets of all calibers and sizes (e.g., .50 caliber, .22 caliber, etc.), and with projectiles larger than bullets (e.g., mortars, missiles, grenade launchers-based ordnance, etc.).
As discussed herein, the materials used for the housing exoskeleton 120 and the deceleration sleeve 130 can be selected based on factors such as the caliber of the bullet, the weapon used to deploy the bullet, the intended target, and other factors. Likewise, the physical characteristics of various components (e.g., the thickness of the various parts of the housing exoskeleton 120 and/or deceleration sleeve 130) can similarly be altered according to these factors.
As mentioned above, the electronics component 110 is encased within a potting material. In embodiments, a polymer potting material can be used to not only encase the electronics component 110, but also to replace one or more of the components of the embodiment of FIG. 1. For example, a polymer can be used with a mold to shape the polymer layer to replace the housing exoskeleton 120, and in certain embodiments, also replace the deceleration sleeve 130 and core 160. In still other embodiments, the polymer can be in the shape of the entire bullet such that the outer jacket 150 is also replaced. In these embodiments, the electronics component 110 encased in the polymer bullet is assembled with the powder charge 200 and primer 300 to form the finished cartridge 400.
As used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.
It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
